Sculpto is a waveform shaping tool allowing powerful direct control over audio. Sculpto displays the waveform of the input audio and lets you draw curves across it to create envelopes that the audio then follows or clips to, or both, in real time, non-destructively and with amazingly low CPU use:

Click Removal: Clipping to an envelope allows to edit out unwanted peaks, such as clicks or room noise.

Transient Shaping: Not getting the impact you need from traditional dynamic tools? Drawing an envelope in Sculpto allows you to visually design the dynamics of the sound. For example, if a snare drum hit isn't snappy enough, draw a new envelope around it with a sharper attack.
